The peaks of a mountain range, acting like rocks in a
streambed, produce ripples in the air ?owing over
them; the resulting ?ow pattern, with crests and
troughs that remain stationary although the air
that forms them is moving rapidly, are known as
“standing waves.”
A) crests and troughs that remain stationary
although the air that forms them is moving
rapidly, are
B) crests and troughs that remain stationary
although they are formed by rapidly moving
air, are
C) crests and troughs that remain stationary
although the air that forms them is moving
rapidly, is
D) stationary crests and troughs although the air
that forms them is moving rapidly, are
E) stationary crests and troughs although they are
formed by rapidly moving air, is

此题如何在C和E中选。我觉得E也不错呀，比C简洁。答案是C。

这道题不能光看简洁性。简洁性是最后一个原则而不是第一个。首先要排除语法和逻辑上的其他问题。

E的错误很隐蔽，主要问题是although的逻辑层次混乱。
C当中的although是属于 crests and troughts 身后的that从句的内部关系， remain stationary although the air .... is moving rapidly, stationary 对 moving rapidly.
而E当中没有定语从句关系，根据平行对称原则， although的左右两边应该都是句子，所以E当中的although的关系就变成了the resulting flow pattern are known....., although they are formed by rapidly moving air了。此时they的指代也不对了。

“根据平行对称原则， although的左右两边应该都是句子”，说的很好。谢了。
